Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1950. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as Boeing's Renton Fuel Farm beginning in the 1950s, housing multiple large underground storage tanks — including two 50,000-gallon Jet A tanks, a 12,000-gallon JP-4 tank, a 2,000-gallon gasoline tank, and a 12,000-gallon reinforced concrete tank that stored waste fuels, waste oil, and waste Skydrol through 1987. Past releases from these former USTs led to soil and groundwater contamination, prompting cleanup under the Standard Cleanup program that has included tank removals, partial tank closures with contents removal, soil and groundwater remediation, demolition, and backfilling. Groundwater monitoring has been ongoing since at least 1986, with additional cleanup actions still required as of 2013. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.

Why Historical Insurance Policies May Be Accessible

Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.

The petroleum and chemical contamination at this fuel farm originated from underground storage tanks installed in the 1950s and operated continuously through the mid-1980s — squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Decades of documented remediation expenditures — tank removals, soil cleanup, groundwater treatment, and long-term monitoring — were incurred to address releases tied directly to those pre-1986 fueling operations. Historical carriers who issued CGL policies to the operator during that window may be obligated both to recover past cleanup costs and to fund the remediation work that remains ahead.

Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
